Alex I am a fairly new to building car models but a long time aircraft modeller.I was asking myself the same question. mM problem was the dash of a Ferrari 599GTB. I tried the making templates with Tamiya tape method but it did not work.I ended up just looking at the part and cutting and applying the decal in sections.It worked perfectly.I have a Fujimi Enzo in work and plan to use the same method.You might want to check out this website lots of good tips here.
